IMPROVEMENT IN DISH-HEATERS.

To all whom it may concern:

Be it known that I, WILLIAM BRAND, of Burlington, in the county of Des Moines and State of Iowa, have invented a new and Improved Dish-Heating Apparatus; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making a part of this specification, in which- Figure 1 is a top view of the improved apparatus with the dishes removed. Figure 2 is a vertical longitudinal section through Fig. 1, taken in the planes indicated by the course of red line a; m. Fig. 3 is a transverse section through Figs. 1 and 2, taken in the vertical plane indicated by the red line 3 y thereon.

Similar letters of reference indicate corresponding parts in the three figures.

This invention relates to an apparatus for heating dishes and keeping warm such things as may be contained therein by means of hot water, and the object of my invention is to heat water by the direct heat of the stove or stoves, and to conduct off the steam through the draft or smoke-pipe of the stoves, thus preventing either the smoke or steam from escaping into the room in which the apparatus is arranged, and while this is the case, the dishes are brought in contact with the boiling water, all as will be hereinafter described.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

In the accompanying drawings, A A represent two stoves, which may be constructed of any desired pattern for burning either wood or coal. The upper ends of these stoves are left open and communicate with the chamber B of an oblong rectangular box, which is constructed as follows:

0 is a horizontal plate, which is provided with openings of various sizes and shapes for receiving the pans or concave-covered dishes, a a a. This plate forms the top of the box,

as shown in Fig. 1. The bottom D of this box may be made convex outside, or flat, but in practice the convex form (shown in Figs. 2 and 3) will be found preferable for collecting the soot, ashes, &c., which rise from the open-top stoves, A A.

Between the top plate, 0, and the bottom plate, D, another plate, E, is interposed, which divides the box into two compartments, B G,

the lower one, B, of which is the smokechamher, and the other, G, the water-chamber, which may be supplied with water by means of a pipe, 0, leading off to a pump or to the streetmain. The cock 0 in this pipe is used to re-- tain the water in this chamber G when a sufficient quantity has been obtained. The smoke is conducted off into the chimney through the pipe I), which is a direct flue for the smoke rising from the stoves A A, and the only escape which is provided. This pipe may be located in the bottom plate, D, at an intermediate point between the two stoves; but, if desirable, it may be placed in any other position where it will form a direct flue for the chamber B. The shallow pan E does not extend the entire length of the box or the smoke-chamber, leaving at one end (shown in Fig. 2) a compartment in which the smoke and heated products of combustion can act directly upon the bottoms and sides of vessels which are set into the holes Otherwise the entire surface of the apparatus is a waterheating surface.

At two points in the top plate of the apparatus are conical cups or steam-domes g g, hollow inside, and secured down to plate 0, over holes which are made therein. These domes are used for the purpose of re ceiving the short pipes h h, which pass down through the plate E, and form communications between the water-chamber G and smoke-chamber B, through which communications the steam which rises into domes g 9 passes and escapes through the smoke-pipe b, as indicated by the red arrows in Figs. 2 and 3, the black arrows indicating the products of combustion. These vertical tubes h h and their steam-domes g 9 should be so arranged with reference to the level of the water in chamber G, that they will collect all the steam arising from the boiling water, and conduct it off as described, and, also, so that the water will not escape through the pipes. This box, which I have described, is mounted upon four legs or standards, is k, the upper ends of which are tapped through projections or fixed nuts jj, and their lower ends pass through the flooring G and receive nuts m on, as shown in the cross-section, Fig. 3. By turning these rods or legs k 75, the box may be elevated or depressed, and by means of this adjustment the water in the shallow pan or chamber G can be brought to a uniform depth, and the entire apparatus leveled.

From this description it will be seen that my apparatus for heating dishes, &c., is very simple in its construction, and well adapted to the purpose for which it is intended. It may be constructed out of any metal capable of resisting heat, and the dishes may be made of any size and shape suited to the requirements of the case. The draft of the flue b being only ordinarily good, all the steam from chamber G and smoke from chamber B will be drawn through the common flue I), and escape up the chimney, instead of into the room in which the apparatus is arranged. A uniform heating of the dishes is secured, without any burning or scorching, so common in the old-style chafingdishes. The stove or stoves consume but little fuel. Hence there is a great reduction in cost over the old-style chafing-dishes, of which my invention is an improvement.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. The combination of chambers G B with a stove or stoves, A, and steam-pipes h h and domes g g, the whole constructed and operating substantially as and for the purposes described.

2. In combination with the horizontal chambers or box herein described, the adjustable standards or legs k 70, for the purpose of keeping the water-pan level, as set forth.

3. The arrangement of stoves A A beneath a shallow horizontal boX, constructed with the dish -holdin g plate 0, water-chamber Gr, smoke-chamber B, and a direct steam and smoke-escape flue, 12, substantially as described.
